Temporary platform

ABSTRACT

Provided is a modular construction kit adapted to construct a raised temporary platform, the modular construction kit comprising one or more floor elements, wherein the floor element comprises a monocoque structure forming a floor section and a flange section, wherein the flange section is adapted to strengthen the floor element and is adapted to be attached to a further element to form a self-supporting floor, without the requirement for a supporting floor frame.

The present invention relates to temporary platforms and modular construction kits for construction of such platforms. The platforms are typically free-standing, and are raised off the ground. Typically the platforms are designed for viewing or observation, display, storage, shows, concerts, and the like. The platforms are advantageous in that they are lighter and stronger than similar platforms known in the art. Moreover, due to the nature of the form and connectivity of the modular components, the platforms can be constructed (and removed) more quickly, and with less heavy machinery, than known temporary platforms.

Temporary viewing platforms for the events industry are known in the art. Such platforms are commonly used at festivals (such as music festivals), sporting events (such as horse racing), polo, golf, and private and corporate events. Temporary viewing platforms are generally used for short term events where a permanent structure is not desired, or permissible.

Temporary viewing platforms are commonly constructed using conventional scaffolding and/or trussing to support a platform. Alternatively, scaffolding and platform structures may be provided which have been adapted for constructing a specific type of structure such as a tiered seating structure as described, for example, in FR2585752.

One problem with many such raised structures is that the supporting scaffolding forms a cross-linked supporting structure, or at least a dense field of vertical supporting legs, which impedes access, for example because it is difficult to negotiate through on foot. As such, any temporary viewing platform constructed using these prior art arrangements provides a raised viewing platform at the expense of rendering useless the area underneath the viewing platform. Furthermore, such structures provide an obstacle to the flow of people at ground level which is problematic for events at which large crowds of people are present.

Another problem with some prior art arrangements stems from the fact that they are either adapted for one specific type or shape of structure or alternatively are not adapted for any particular type or shape of structure. The problem with systems which are not adapted for any particular type or shape of structure is that they are usually difficult and time consuming to construct into a desired structure. Conversely, the problem with systems which are specifically adapted for a particular type or shape of structure is that they do not provide much in the way of flexibility for providing different types and shapes of structure as desired. For example, for certain uses an elongate linear viewing platform may be desired, e.g. for a stage. For other uses a non-elongate viewing platform may be desired, e.g. to view out in all directions from a specific location. The required type or shape of final structure may also be determined by the space available and the contours of the land on which the temporary viewing platform is to be constructed.

Another problem with some arrangements is that they are adapted to be mounted to another structure such as a side of a building rather than being free-standing.

Yet another problem with some prior art arrangements is that they are not aesthetically pleasing, at least from certain angles. For example, supporting scaffolding is often visible from at least a rear side of a temporary viewing structure which is unsightly and undesirable, particularly at exclusive events.

Some of these problems have been solved to a certain degree. For example, WO 2009/147004 discloses a temporary viewing platform which can be erected from a modular construction kit, and is adapted for hexagonal or linear shapes, such that all-round viewing is possible. However, such platforms are still desired to be lighter and more portable, in order to increase flexibility of use, ease of construction and, facilitate more pleasing aesthetic design.

US 2005/0,120,650 discloses a ‘double floor’ structure. However this structure is not designed to be raised, since the first floor of the structure is formed on a base layer, such as the ground. Moreover, the space between the floors is very small, and is designed to allow space for wiring or air conditioning pipework, and could not be occupied by people. Finally, the structure is not self-supporting, and the upper floor is supported by a support means provided on the lower floor.

GB 2,472,201 A discloses a combination floor plate with integral connectors. The floor plate is intended to be laid across an existing floor or area of ground, and is not self-supporting, nor is it adapted to form raised platforms. It is typically employed as temporary protection for existing surfaces, such as during refurbishment.

GB 2,433,519 discloses a temporary flooring system, which is designed to sit directly onto a floor, or piece of ground, using a flange section of the floor pieces as a leg. The system is therefore not adapted to be raised or self-supporting.

Embodiments of the present invention aim to solve the aforementioned problems. In particular, it is an aim of certain embodiments of the present invention to provide a modular construction kit which has improved transportability, improved speed and ease of construction, and improved speed and ease of de-construction thereafter for further transport and re-use. It is a further aim to provide a modular construction kit which is adapted to construct a specific range of types and shapes of temporary platform. It is a still further aim to provide free-standing, raised platforms, the underside of which is readily accessible by people on foot (i.e. under which people can readily walk) at ground level, and which are aesthetically pleasing from a wide variety of angles.

Having identified the previously described problems associated with various prior art arrangements for platforms, the present applicant has developed a modular construction kit which solves all these problems.

Accordingly, the present invention provides a modular construction kit adapted to construct a raised temporary platform, the modular construction kit comprising one or more floor elements, wherein the floor element comprises a monocoque structure forming a floor section and a flange section, wherein the flange section is adapted to strengthen the floor element and is adapted to be attached to a further element to form a self-supporting floor, without the requirement for a supporting floor frame.

In the present context, the term ‘raised’ means that at least one floor of the platform is adapted to be raised such that none of the floor elements forming the raised floor are in direct contact with the floor or ground on which the platform is constructed. The height to which the floor may be raised is not especially limited. However, typically it is able to be raised sufficiently to allow people to walk beneath it. Thus, the floor elements may be lifted from contact with the ground by means of leg elements, stair elements and/or other raising means. The raising means are not especially limited, provided that they are capable of raising the floor, as detailed above. The floor sections forming the raised floor of the temporary platform remain level and are typically suitable (safe) for people to walk or stand upon. The temporary platform is self-supporting. In this context ‘self-supporting’ means that none of the floor elements forming the raised floor of the temporary platform need to be in direct contact with the floor or ground on which the temporary platform is constructed, and the platform still remains suitable (safe) for people to stand or walk upon without the requirement for a supporting frame or other floor support means.

Thus, the present kit enables construction of a temporary platform, such as a free-standing viewing platform. In the present context ‘temporary’ means that the platform is readily erected and readily dismantled after use. Typically the temporary platform is re-usable. The structure is self-supporting due to the light and strong floor elements, which are of a unique monocoque construction, the special flange (which may also be termed the flange part or flange section) providing a dual function of strengthening the floor and attaching the floor elements together. In this way the floor plates (which may also be termed floor parts, floor panels, or floor sections) are able to form an even, strong floor, whilst the floor elements as a whole cooperate together so as to be self supporting. The floor elements are thus load-bearing parts of the platform and are intended to support not only the weight of articles placed on the platform (and/or the viewing public) but also bear the load of the platform itself This obviates the need for a frame, gantry, or other supporting structure that would increase the number of parts, the complexity, the size, the weight, and/or the construction/dismantlement time of the kit.

In the invention, the flange section is adapted to strengthen the floor element. In this context the term strengthen is not especially limited, provided that some form of structural support is provided. Thus, strengthen may mean an improvement in the load bearing capacity of the floor element (either alone, or when in use in a platform), and/or an improvement in: the resistance to deformation, breaking, cracking, stretching, crushing, warping, bending or the like, or any other resistance that helps to maintain the integrity of the floor element and/or the platform. Improvement in this context means improvement as compared with a floor element not comprising a flange section, or with a floor element with a flange section that is not integral with the floor section, or with a floor element that does not have a monocoque structure.

In some embodiments, the flange is strengthened by providing a strengthening plate on the flange section. In the present context ‘strengthening’ means any kind of strengthening as defined above, and especially stiffening. The strengthening is typically sufficient to allow thinner or shorter or lighter flange sections, and/or lighter floor sections. The strengthening plate is typically, but not exclusively, situated on the flange section only (see FIGS. 1 a and 1 b—the CUD and C-plate), but in some embodiments it may be a single plate situated on both the flange section and the floor section and extending around the angle between the two sections, or may be two plates, one on each section. In other embodiments, the strengthening plate may be situated on the floor section only, provided that sufficient strengthening of the flange section is thereby achieved. Typically, the strengthening plate is situated under the surface of the monocoque, as shown in FIGS. 1 a and 1 b. The nature of the strengthening plate is not especially limited, but typically it is formed from a plurality of layers laminated together, and/or from unidirectional fibres. In typical embodiments, it is formed from carbon, such as laminated carbon, and/or carbon fibres. In these embodiments the plate is termed a carbon plate, or C-plate.

In further embodiments, the floor section is strengthened by providing it with a strengthening portion. In the present context ‘strengthening’ means any kind of strengthening as defined above, and especially stiffening. The strengthening is typically sufficient to allow thinner or shorter or lighter flange sections, and/or lighter floor sections. The strengthening portion is typically, but not exclusively, situated at the end of the floor section distal to the flange (see FIGS. 1 a and 1 b—the pultrusion). Typically, the strengthening portion is situated under the surface of the monocoque, as shown in FIGS. 1 a and 1 b. The nature of the strengthening portion is not especially limited, but typically it is formed from a plurality of layers laminated together, and/or from unidirectional fibres. In typical embodiments, it is formed from carbon, such as laminated carbon, and/or carbon fibres.

The floor elements of the invention may comprise one or both of the strengthening element and the strengthening portion. The floor elements are typically manufactured by pre-forming the strengthening plate and/or the strengthening portion, and then laminating the strengthening plate and/or the strengthening portion to the floor element in a mould to form the monocoque floor element.

In the present context, the term monocoque is intended to mean a form or structure that supports structural load by using an object's exterior, and/or a form or structure in which the chassis is integral with the body. This is as opposed to using an internal frame, truss, or the like that is then covered with a non-load-bearing outer section, skin or the like. In the present context the term monocoque is considered to be synonymous with structural skin, stressed skin, unit body, unibody, unitary construction, or Body Frame Integral (BFI) construction.

The present invention will now be described in further detail by way of example only, with reference to the accompanying drawings in which:

FIGS. 1 a and 1 b show examples of a floor element showing a floor plate, a flange, a strengthening plate (CUD or C-plate), a strengthening portion (unidirectional pultrusion) and the monocoque structure of the element.

FIG. 2 a shows a sandwich construction, which may be used for the monocoque structure in the present invention. A structural panel is shown, consisting of two relatively thin, dense, high strength and parallel sheets of structural material with their faces bonded to and separated by a relatively thick, lightweight core such as honeycomb or foamed plastic.

FIG. 2 b shows a closer view of the typical honeycomb structure. Two load-bearing skins are separated by a core of stiffening material, generally lightweight, to provide high strength, and rigidity. The two load-bearing materials typically have different physical properties.

FIGS. 3 a to 3 c show exemplary hexagonal viewing platforms formed from kits of the present invention—in these exemplary structures, the platform is raised from the ground using supporting legs, and the floor elements are formed as equilateral triangles to facilitate formation of a hexagonal structure with all-round viewing capacity.

FIG. 4 a shows an example of a connection for fixing a leg element to one floor element or two adjacent floor elements. FIGS. 4 b and 4 c show how adjacent floor elements may be adapted to define an appropriately shaped hole into which leg elements may be fixed.

FIGS. 5 a to 5 e show exemplary kits formed from 1, 2, 3, 4 and 5 floor elements (panels) respectively.

FIGS. 6 a and 6 b show exemplary kits formed from non-linear tessellating floor elements, in this case curved elements.

FIGS. 7 a and 7 b show exemplary kits formed from two or three different shaped floor elements, in this case rectangular and trapezoidal, and triangular rectangular and trapezoidal, panels respectively.

The floor elements are not especially limited, provided that they are of a monocoque construction and comprise the appropriate floor plate and flange in a single element, i.e. an integrated element that is formed in a single piece. Thus the floor elements can be any shape or size, and this may be selected depending upon the type of platform required, the number of viewers and/or the weight bearing load required, and/or the direction or directions of viewing required. Typically the floor elements have a side length of from 100 mm to 15,000 mm. The depth of the floor elements is also not especially limited, and may be selected depending upon the type of viewing platform required, and typically upon the weight bearing load required. Typically the floor elements have a depth of from 10 mm to 1,000 mm. The weight of the floor elements is not especially limited, and may be selected depending upon the type of platform required, and its method of construction. Typically, the weight of the floor elements is from 10 kg to 500 kg.

The shape and configuration of the flange part is not especially limited, provided that it is capable of strengthening a floor element as compared with a floor element with no flange part, and provided that it is capable of being attached, joined or fixed (either directly or indirectly—i.e. directly by attachment with bolts, screws or other like fixing means, or indirectly using a fixing element as described below) to a further element of the kit. Typically it is adapted to be attached to the flange part of another floor element to join together two or more floor elements such that the floor parts form a suitable floor. However, it may also be adapted to be fixed to other elements, such as handrail elements or stair elements, or to two, or more, or all elements in the kit. Typically the flange part forms an angle with the floor part, and more typically the angle is between 80-100°, most typically approximately 90°. The flange section is typically adapted so that it protrudes below the floor section, such that it does not interfere with the even nature of the floor. However, in some embodiments, the flange part may protrude above the floor part and form a fixing point for further floor pieces. Such further floor pieces are optional and would not need to be load bearing, but may be of interest for aesthetic, or other reasons in some instances. An example of a floor element showing a floor plate, a flange section, and having a monocoque structure is shown in FIG. 1. In this diagram an optional box section is shown, which may enable attachment of the further floor pieces if the flange part were protruding above the floor.

The structure and materials forming the floor elements used in the present invention are not especially limited, provided that they do not prevent the elements from constructing a suitable platform in accordance with the invention. Typically, the floor elements comprise a core material surrounded by a structural skin or shell, thus creating a monocoque structure (see FIG. 2 a and FIG. 2 b). In this arrangement, the core material is typically low density, being designed to carry shear loading, whilst the surrounding structural skin is designed to carry the compressive and tensile loads.

The materials from which the skin is formed are not especially limited, provided that they do not prevent the elements from constructing an appropriate platform in accordance with the invention. Thus a sandwich-type structure may be employed, as shown in FIGS. 2 a and 2 b. The skin may typically comprise a strong, yet lightweight material, such as a lightweight metal (e.g. aluminium or titanium), but more typically, composite materials are employed. In the present context, composite materials means materials that are formed from two or more constituent materials with significantly different physical or chemical properties. Typically these physical or chemical properties remain separate and distinct on a macroscopic level within the finished structure. Desirable composite materials include, but are not limited to, light and strong materials, such as lightweight metal (e.g. aluminium or titanium), carbon-based materials (such as carbon fibre, nanotube fibre and graphene), glass fibre (e.g. e glass or s glass), spectra fibres, PVA fibre, structural foam, wood (e.g. balsawood, plywood, bamboo and the like), man-made fibres (e.g. aramid (Kevlar or Twaron) and the like), boron fibre, cellulose fibre, combinations of two or more of the above, and woven, stitched, braided or 3d fabrics formed from one or more of the above. A combination of woven carbon and glass fibre is particularly preferable.

The core material is not especially limited, provided that the function of the element is not unduly impaired, and may comprise metal (e.g. aluminium), a foam, an aerogel, a woven 3d structure, wood (e.g. balsa), glass fibre, pultrusions (unidirectional materials, such as carbon or glass used to add stiffness e.g. to the ends of flanges or floor sections), laminates (e.g. carbon laminates formed from multiple layers of carbon materials) and other light materials. End-grain balsa wood is particularly advantageous. It has exceptional bond, high impact and fatigue resistance with excellent strength/stiffness and lightweight properties. It also has a high aspect ratio and directionally aligned cells such that the grain is oriented in the direction of the maximum stress. The structure of the core is not especially limited, and may be arranged either as a block or as a structurally efficient supporting member such as a honeycomb. An exemplary structure is shown in FIG. 2 b. The core is typically held within a resin matrix to help bind the core materials together. The resin may further add to the strength of the composite material. Typical resins include those formed from polyester, epoxy, vinyl ester, phenols, and polyurethane.

The floor elements of the platform are typically fixed together via their flange sections. Typically adjacent flange sections are attached to each other. However, not all adjacent flange sections need to be attached. The skilled structural engineer will appreciate the necessary attachment points based upon the nature of the platform, and the load that the specific platform is designed to bear.

The attachment of the flange parts is not especially limited, provided that it does not adversely affect the structural integrity of the platform. The flange parts may, for example, be bonded (e.g. with an adhesive substance) or mechanically fastened together (e.g. using bolts, screws, rivets, or the like). Typically the flange parts are held together using a fixing element, which fits reversibly into a hole between two flange parts as defined when two floor elements are placed adjacent to each other. The hole may be defined by missing sections of the flange parts, or by curving of the flange parts, or by thinning of the flange parts, or the like. Alternatively, the fixing element may be a connection. The connection may be any fastening means adapted to fasten the two flange parts together. The fixing element is, however, not limited, and may be any article, part or insert that is adapted to fit in a hole formed from the two adjacent floor elements, or to fix the two adjacent floor elements together. Typically the fixing element comprises a peg or dowel which may slot into the hole, holding the two floor elements together. The fixing element may hold the two elements together alone, without the need to be held in place in the hole, or may be held in place using an attachment means, such as adhesive, bolts, screws, rivets or the like. Alternatively, the fixing element may employ a snap-fit type connection, or a complementary male and female type connection. The fixing element may be a leg (see FIGS. 4 a, 4 b and 4 c), which serves to distance the floor from the ground. In this arrangement, not all attachment holes need to be fixed using a leg, and some may be fixed using a dummy leg (a leg which does not need to bear (or does not bear) any load) or with the dowel, peg or other fixing element.

The aforementioned modular construction kit is not only capable of, but is indeed specifically adapted to, produce a particular range of types and shapes of temporary platform, and especially types of free-standing temporary viewing platform. Typical examples include, but are not limited to rectangular, circular, elongate, hexagonal and square shaped horizontal free-standing viewing platforms and combinations of these.

It is further preferred that the temporary platform of the invention has at least one floor raised sufficiently above ground level for people to walk under (see FIGS. 5-7). It is further preferred that the temporary platform of the present invention is a multi-storey platform (having 2 or more storeys connected by stair elements—see FIGS. 5-7). The temporary structures of the present invention are particularly light and strong and making them especially useful for constructing such multi-storey temporary platforms.

By providing a modular construction kit which is adapted to form a specific range of types and shapes of temporary platform, the modular kit is more readily constructed than, for example, systems which are not adapted for any particular type or shape of structure. The structures provided by the modular construction kit allow a degree of flexibility that is absent from systems which are specifically adapted for one particular type or shape of structure. Typically, but not exclusively, in order to provide this specific adaptability the invention provides floor plates which have a rectangular shape, a square shape, an equilateral triangular shape, a right-angled triangular shape, and/or an isosceles trapezoidal shape. Such floor plates are ideally adapted for constructing rectangular, square, hexagonal and/or linear shaped platforms, or other shapes (such as irregular and/or modular shapes), and shapes which include combinations of two or more of the above shapes (see FIGS. 7 a and 7 b).

According to one embodiment, the invention provides a kit comprising at least one floor element, at least two leg elements and at least one stair element. Such a kit typically, but not exclusively, also comprises one or more handrail elements. In a further embodiment, the invention provides a kit comprising at least two floor elements, at least one fixing element, at least two leg elements and at least one stair element. Such a kit also typically, but not exclusively, comprises one or more handrail elements.

A further kit of the invention comprises at least six floor elements having an equilateral triangular shape. This kit is particularly well suited to the construction of a hexagonal shaped viewing platform. In some embodiments, the kit may comprise a larger number of smaller triangular floor plates. This can be advantageous because it allows for narrow elongate viewing platforms to be readily constructed using the same elements. Furthermore, in this arrangement, the floor elements may be smaller, and are thus easier to handle during construction and more readily transportable. Thus, the invention also provides a kit comprising at least twenty four floor plates having an equilateral triangular shape. This kit is particularly well suited for the construction of a hexagonal shaped viewing platform in which six floor elements form a central hexagonal structure with the remaining eighteen disposed around the central hexagonal structure in an alternating orientation to form a larger hexagonal structure for the hexagonal viewing platform.

One problem with this arrangement is that a relatively large number of floor plates are required and all these floor plates must be arranged and supported to form the viewing platform which can be relatively time consuming.

Accordingly, in one particular advantageous embodiment the eighteen triangular floor plates disposed around the central hexagonal structure can be replaced with five isosceles trapezoids and a stair element, or six isosceles trapezoids. Each isosceles trapezoid has a base twice as long as its top with sides of equal length, the sides also being equal in length to the top of the trapezoid. As such, each isosceles trapezoid has an area three times the area of each central equilateral triangular floor plate. Thus the number of floor plates required for a hexagonal viewing platform is reduced from twenty four to eleven or twelve. According to this embodiment the modular construction kit comprises at least six equilateral triangular floor plates and at least five or six isosceles trapezoid floor plates. This has been found to be a good compromise between the required size for the floor plates and the required number of floor plates to construct viewing platforms having a suitable size. The trapezoid floor plates have also been found to be useful in forming long thin platforms such as walkways without requiring as many joints as with their triangular shaped counterparts.

Yet another option to further reduce the number of floor plates is to replace the six central triangular floor plates with a single hexagonal central floor plate. According to this embodiment the modular construction kit may comprise at least one hexagonal floor plate and at least five or six isosceles trapezoid floor plates. The hexagonal floor plate should have a side length equal to the top of each isosceles trapezoid. Alternatively, the central hexagonal floor plate may be surrounded by eighteen triangular floor plates in order to construct a hexagonal viewing platform.

Yet another option is to use two isosceles trapezoid floor plates to form the central hexagonal structure with five or six further isosceles trapezoid floor plates disposed around the central hexagonal structure. According to this embodiment the modular construction kit may comprise at least seven or eight isosceles trapezoid floor plates. As referred to above, the place of the eighth isosceles trapezoid floor plate which would finish the regular hexagon shape may be taken by a stair element in raised platforms, or by a final eighth isosceles trapezoid floor plate when no stair is required.

Various other configurations of floor elements will be apparent to the skilled person, depending upon the nature of the viewing platform required. Thus, floor elements comprising a floor section having any other shape may be employed, and kits having floor plates of a plurality of different shapes are envisaged (see FIGS. 7 a and 7 b). Thus, kits comprising floor elements which have a floor plate which is triangular, rectangular, square, rhomboid, parallelogramoid, pentagonal, hexagonal, heptagonal, octagonal, nonagonal, decagonal, and circular are also encompassed by the invention. Floor elements may be any of the above shapes in complete form, or in semi or partial form (such as a semi-circle or the like). Floor elements may also be formed from non-linear tessellating shapes (see FIGS. 6 a and 6 b). Typically, but not exclusively the floor plates in a kit are all the same shape, but kits with two or more shapes, three or more shapes, four or more shapes etc. are also envisaged.

The kits of the present invention may comprise further elements, depending upon the nature of the platform to be constructed. The further elements are typically, but not exclusively, formed from the same materials as the floor elements. In some embodiments, the further elements are provided with a flange to facilitate construction. Exemplary further elements are discussed below.

Further elements may include one or more handrail elements, which may be adapted to be mounted to the floor elements around a circumference of the floor for preventing a user from falling over an edge of the temporary platform. Such handrail elements are typically, but not exclusively, attached to the flange section of the floor elements. The method of attachment is not especially limited, and any attachment means mentioned above may be employed, such as adhesive, bolts, screws, rivets or the like.

In some embodiments, particularly those where the platform is designed to have multiple storeys, the kits may further comprise one or more stair elements. The stair elements may be adapted to be mounted to one or more of the floor elements, whereby a user can climb the stair element to access a higher storey. Such stair elements are typically, but not exclusively, attached to the flange section of the floor elements. The method of attachment is not especially limited, and any attachment means mentioned above may be employed, such as adhesive, bolts, screws, rivets or the like. The stair element may itself also comprise, or be adapted to be attached to, one or more handrail elements, if desired.

As mentioned, the kits may also be specifically adapted to provide a platform which is sufficiently raised such that members of the public can readily stand or walk under it. Such a platform does not provide an obstacle to the flow of people at ground level which would otherwise be problematic for events at which large crowds are present. Alternatively, the space underneath the temporary platform may be used, for example, as a bar or the like. In such embodiments, to ensure that members of the public can readily walk under the platform, the kit may comprise legs which are at least 6 feet (1.829 meters) long which can be orientated in a vertical direction for supporting the platform. More preferably, the legs are at least 7, 8 or 9 feet (2.134, 2.438 or 2.743 meters) long. In some instances shorter legs may be employed, provided that these legs are extendable to at least 6, 7, 8 or 9 feet (1.829, 2.134, 2.438 or 2.743 meters) in length. For example, the legs may be telescopic. Such telescopic support legs may be adapted to be extendable and fixed at a number of different lengths according to a desired use.

The legs and the floor elements must be strong enough such that the platform can be supported with a relatively small number of legs. A dense configuration of legs is preferably avoided as this would render the space underneath the platform less useful, and provide an obstacle to the flow of people at ground level. For example, according to one preferred arrangement a hexagonal viewing platform is provided with seven support legs, one at each point of the hexagon and one in the centre of the hexagon. Preferably the legs are at least 6 feet (1.829 meters) apart to allow people to walk under the temporary platform without being unduly impeded.

The temporary platforms of the present invention are more aesthetically pleasing than previous arrangements using, for example, conventional scaffolding or the like. The pleasing aesthetic quality of the present invention is achieved by providing the combination of features described previously. The triangular, trapezoid, hexagonal, linear, and other shaped structural components of the platforms in combination with a relatively disperse supporting structure has been found to be particularly aesthetically pleasing.

Embodiments of the present invention can be used to create a wide variety of different temporary platform structures comprising hexagonal decks, rectangular decks, elongate linear stages, and other configurations. This is advantageous when compared with known systems which are not adapted to produce any specific type/shape of structure or are adapted to form a single structure or variants of the single structure such as a shorter or longer stage of the same shape. The components of the present modular construction kit are adapted to be readily attached and taken apart in order to allow easy construction and transportation which is required for such temporary structures as opposed to more permanent building structures. For example, the components may be adapted so as to be attachable using nuts and bolts, snap-fit type connections, or complementary male and female type connections rather than using, for example, nails, screws, welds, adhesive or cement as in more permanent constructions.

Further elements that provide extra functionality to the kits may be included. Exemplary further elements include one or more of the following:

-   -   Canting feet which may fit onto the base of the legs—allows for         leveling of legs locally;     -   Padeyes (adapters between legs, handrails, stays, etc.);     -   Tenting (e.g. top, side walls, awnings)—tensile, stretch fabric         or composite mouldings for weather-proofing and aesthetics (see         FIG. 3);     -   Blinds and blind channels, to temporarily close out the weather         on the sides of the structure     -   Lift for disabled access     -   Heaters for warmth; and     -   Lighting.

Still further elements that aid in construction and dismantling the platforms may also be included in the kits of the invention. Examples of these include:

-   -   Panel lifts formed from steel cables with winches for lifting         floor elements and other elements into place;     -   Ladders to get construction workers into place to fix the parts         together;     -   Nuts/bolts/screws/adhesives and/or other fixing means;     -   Staying cable (steel or composite cable) to create cross bracing         to reduce movement of the structure; and     -   elbow braces and/or cross braces to reduce movement but allow         people to walk through the structure.

Particularly advantageous aspects of the further elements of the kits of the invention will now be described by way of example only.
